Recently, liquid crystal displays have been spotlighted as next generation advanced display devices having low power consumption, good portability, technology-intensive, and high added value.

Among such liquid crystal display devices, an active matrix liquid crystal display device having a switching element capable of controlling voltage on / off for each pixel is attracting the most attention due to its excellent resolution and video performance.

In general, a liquid crystal display device forms an array substrate and a color filter substrate through an array substrate manufacturing process for forming a switching element and a pixel electrode and a color filter substrate manufacturing process for forming a color filter and a common electrode, respectively. It is completed through the liquid crystal cell process through a liquid crystal between them.

The driving principle of the liquid crystal display device uses the optical anisotropy and polarization property of the liquid crystal. Since the liquid crystal is thin and long in structure, the liquid crystal has directivity in the arrangement of molecules, and the direction of the molecular arrangement can be controlled by artificially applying an electric field to the liquid crystal.

Accordingly, when the molecular arrangement direction of the liquid crystal is arbitrarily adjusted, the molecular arrangement of the liquid crystal is changed, and light is refracted in the molecular arrangement direction of the liquid crystal due to optical anisotropy to express image information.

Here, the TFT array formed on the lower substrate 14 serves to transmit and control an electrical signal, and the liquid crystal 13 controls the degree of light transmission by varying the molecular structure according to the applied voltage. The light controlled through the above process passes through the upper substrate 12 on which the color filters are arranged, and is displayed in a desired color and image.

The lower polarizer 15 and the upper polarizer 11, which are polarizers, are further provided on both surfaces of the liquid crystal display including the lower substrate 14, the liquid crystal 13, and the upper substrate 12.
